Three Azalís, among them Siyyid Muhammad-i-Isfahání, the Antichrist of the Bahá'í Revelation, are murdered by seven Bahá'ís. [BBD163; BKG3256 DH41; GPB189; RB3:235]

Siyyid Muhammad Isfahání, Nasr’ulláh Tafríshí, Áqá Ján Ka’j Kuláh and Ridá Qulí these four kept vigil near the land gate to ensure no one would meet Bahá’u’lláh. They kept watch from the second story window of a building overlooking the land gate so that if a pilgrim, after spending some six months traveling on foot, intended to enter the city they could somehow prevent his entrance. This situation lasted for some time. After two years and a few months, Bahá’u’lláh was released from the prison. Some of the friends, including Salmání, decided to get rid of these enemies and during the night went to their place and killed Siyyid Muhammad, Áqá Ján and another person.

See BKG330, DH44 and RB3:239 for the fate of the murderers, who are imprisoned for seven years.

Bahá'u'lláh completes the revelation of The Kitáb-i-Aqdas in the southeast corner room of the house of `Údí Khammár. [BBD132; BKG351; DH46; GPB213; RB3:275; SA248]

There is evidence to suggest that at least some of the work was written earlier as confirmed by the book's reference to the fall of Napoleon III in 1870 and there is further evidence to suggest that parts of The Kitáb-i-Aqdas were revealed as early as 1868. [SA16–17, 248]

For the significance of The Kitáb-i-Aqdas see BKG351–3, BW15:87–91, GPB213–15 and RB3:275–399.

For analyses of its significance, content and application, see RB3:275–399 and SA248–52.

The Law of the Huqúqu'lláh that had first been ordained by the Báb in the Persian Bayán, chapter 19 of unit 5, was reiterated in the Kitáb-i-Aqdas, verses 227-233 and in the Questions and Answers.

At first Bahá'u'lláh declined to accept the Huqúq from the believers stating that the funds were not needed. [Huqúqu'lláh: The Right of God p9]

"After the Kitáb-i-Aqdas had been revealed in response to the pleas of the friends, Bahá’u’lláh withheld it from publication for some time and even then, when a number of devoted Bahá’ís, having learned of the law, endeavored to offer the Ḥuqúqu’lláh, the payment was not accepted. The Tablets of Bahá’u’lláh show His acute consciousness of the way in which material wealth has been permitted to degrade religion in the past, and He preferred the Faith to sacrifice all material benefits rather than to soil to the slightest degree its dignity and purity. Herein is a lesson for all Bahá’í institutions for all time." [Message from the Universal House of Justice dated 25 March, 1987]
